It is completely illegal for a police officer to pretend to be an attorney; it's actually illegal for anyone to pretend to be an attorney (in the situation of a suspect asking for an attorney.) The cops can lie to you about a great many things, but they cannot lie to you about the person you are talking with being an attorney. Any judge would probably immediately declare a mistrial if they found out that had happened, and anything you said to the fake attorney would be deemed inadmissible.
